Our house was built by a woman who lives in California. She built it intending to live in it herself. However, when she completed the projected, she decided that it was too small. She is building another one now. Anyways, because she was intending to live in California, the house wasn't "winter proofed." We didn't have too many issues with this other than the door. Last winter, condensation would gather inside the door. It would drip down and gather underneath the door and freeze. Since ice expands, the door would be pushed up and hit against the stud above it. Closing and opening it was super difficult.
